Abstract: 1,257,227. Pivoted-calliper disc brakes. AUTOMOTIVE PRODUCTS CO. Ltd. 17 March, 1970 [2 April, 1969], No. 17228/69. Heading F2E. A fixed support 11, Figs. 1 and 4, has a flat face 16 in which are two threaded holes 17. A hinge piece 18 comprising a hinge barrel 19 and shank 20 has two holes 21 larger than, but respectively centred with, the threaded holes  17, when the shank 18 is secured by a clamping plate 22 and set-screws 24, Fig. 2, to the support. A calliper 12, Fig. 1, has two arms 2'6, 27, of which the upper, 26, rests on the hinge barrel 29, and the lower, 27, embraces the head 32 of a hinge pin 31. The pin extends through a hole 28 in arm 26 and is held with its head in contact with barrel 19 by a spring 33 cooperating with a washer 34 and clip ring 35. Brake pads 13, 14, Fig. 2, carried by metal backing plates 36, 37 respectively, are located by a rod 38 traversing calliper 12; plate 37 abuts against part of the calliper, while plate 36 is acted on by a piston (not shown), movable by liquid pressure. A lever 42, Fig. 2, for mechanical application, is pivoted on the calliper. The invention ensures that the surfaces of pads 13, 14 are set parallel to the surfaces of brake disc 10 when the brake is first assembled During assembly, the hinge piece 18 is first lightly clamped between support 11 and plate 22, such clamping being sufficient to hold the hinge piece when no load is applied thereto. The brake pads 13, 14 are then applied to disc 10 by the brake-applying means. The application of this load serves to move the calliper 12 and hinge piece 18 slidably relative to support 11, the hinge pin 31 thus moving approximately normal to the plane of disc 10. The set-screws 24 may now be tightened. Modifications (mentioned only).-Only a single set-screw need be provided. Means other than the clamping plate 22 and setscrew(s) may be used. Other arrangements for mounting the calliper on the hinge piece may be used.

Abstract: 1297699 Data storage SIEMENS AG 17 March 1970 [18 March 1969] 12658/70 Heading G4C [Also in Division H3] In a circuit which blocks spurious pulses occurring between perodic data slots, e.g. pulses resulting from redundant flux charges in a magnetic tape system and occurring between adjacent bits of the same value, the blocking period is controlled by a disconnectible circuit in dependence upon the rate of occurrence of ouput pulses. In Figs. 2 and 3 the leading edges of pulses N act via a Nand gate G4 of a bi-stable circuit G3, G4 to effect setting to the state in which A1 is "zero" and A2 "one". This enables a Nand gate Gl so that the positive going edge of the pulses is inverted in G1 and cuts off TO. After a delay t, capacitor C has charged to the threshold level of Nand gate G2 and the "zero" output of this restores the bi-stable circuit. Pulse Al thus lasts from the end of the delay until the leading edge of the input pulse and the output M, which is used in means not shown to control the blocking, is extended to the trailing edge of the input pulse. In order to adjust the blocking period to accord with the data rate represented by T, the charging supply is varied inversely with the rate. The supply is obtained from the pulses M by a circuit (Fig. 4) in which the pulses are amplified at V and filtered by C2, C3, R3 to obtain an average value which is taken out at US via an emitter follower E.F. During the starting period a fined voltage at US may be provided from ST via T3. This is switched in by changing the state of a bistable circuit G8, G9 to short the base of EF1 through T5 and to remove the short through T4 at the base of EF2. To allow for pulses of different duty cycle the M pulses may be obtained by combining in gate G6 (Fig. 4) pulses M1, M2 of different delay obtained from two circuits used alternately (Fig. 5, not shown).

The coupling accommodates limited relative movement between the sealing surface and the pipe 18. Fig. 1 shows the coupling 10 held in its retracted inoperative position, with the valve 19 closed, against the action of springs 11, by a mechanical latch in a powered pneumatic piston and cylinder assembly 12. As shown, the valve comprises a disc 20 mounted on a pivot 32 which is carried on slidable sprung trunnion blocks 33. The valve seat includes a sealing ring 30 held between rings 24, 25 which are further sealed by a ring 31. A bifurcated member 40 mounted on a shaft 45 attached in the bore 46 of a fixed mounting plate 13, has internal opposed pairs of studs 41, 42 which ride in slider tracks 35, 37 and a pin riding along a slot 38 on a slide member 34 fixed to the valve disc 20. The mechanical latches in the assembly 12 are unlocked by a small axial contraction which is accommodated by elongate holes 44, the bifurcated member 40 riding against a spring 47. During subsequent extension of the coupling under the action of the springs 11 the valve disc 20 is urged axially from its seat 22 by the connecting link 40 until the trunnion blocks 33 reach the end of their housings. The studs 42 are urged along the curved slider track 37 pivoting the disc 20 about the pivot 32 through 90 degrees when the studs 42 slide from the track 37 into the straight track 35. Further angular displacement of the disc is prevented by the studs 41, 42 but further axial motion needed to seat the abutment seal 15 is accommodated by movement of the studs 41, 42 along the track 35. In another embodiment, a pair of slider track members (34a, Fig. 3, not shown) are mounted on the disc 20 and the straight slider tracks terminate in arcuate camming sections. Depending from the bifurcated links (40a) are the arms of a spring housing (58), the springs of which urge the valve disc in its closed position. The sealing member 31 is replaced by a portion of the disc seal which extends between the rings (24a, 25a).
